Serving the mobile user in massive MIMO system
2021 13th International Conference on Wireless Communications and Signal Processing (WCSP)（2021）
Abstract
In massive multiple-input multiple-output (MIMO) system, the beam is more directional, and the width becomes narrow as the number of antennas increases. In such case, a moving user equipment (UE) will easily leave the coverage of the beam, causing the existing channel status information (CSI) to be outdated. If the CSI is not updated timely, the transmit rate will degrade due to the absence of acc...
